Update:

So I finally got a bit of good news the other day.

Supposedly, the second head assembly that my dealer has been waiting for all this time has finally made it over from Japan and should now be at SOA in NJ. From there it's being sent to Subaru of NE and then off to my dealership. Not sure what the time frame for shipping and repair is, but I'm hoping that it'll only be a couple more weeks at the most.

So far its been over 3 months...

So far the tsb relates directly to the 2.5 na fb motors and it is replacing piston rings. TSB 02-143-13. But the oil consumption forms for the 2.0 and 2.5 fb motors lists 02-143,144,145,146-13. So I'm gonna assume 144, 145,146 tsb's will release shortly and deal with the 2.0 in different models would be my guess. Our field engineer and a rep at subaru hinted to this coming down the pipe for awhile now. Just an fyi

No, rings are not the valve. I believe what you're referring to is the Positive Crankcase Ventilation (PCV) valve, which can also cause oil consumption if it's bad.

Replacing the PCV valve is a significantly easier job than replacing rings. I can replace a PCV myself, but replacing rings is beyond my shadetree mechanic abilities.

Very interesting. I would also love to read these TSBs.

BTW, there's also a TSB for the Legacy and Outback.

Stolen from subaruforester.org:
Quote:
This from the description: "Bulletin Description: This bulletin provides information regarding a change made to the surface treatment applied to the oil control piston rings for 2.5L FB engines. The change was made as a result of some limited findings of unanticipated wear of these rings. Oil consumption will be higher than normal and consistent, if this wear occurs, the condition remains until repair. Unusual swings or variations in oil consumption are not consistent with this condition and may be the result of vehicle usage rather than the condition described here. Additional information is supplied in this bulletin to assist in the assessment and determination if vehicle usage is a reason for this varied oil consumption."
Ironically, the Forester oil burning thread started back in June 2011 regarding consumption in an MY2011, but 2011's are not mentioned in the TSB. Where's the love Subaru?

Your consumption will probably have to exceed SoA's oil consumption guideline for them to do anything.

Japan sure is slow to react to thngs these days. Funny "subaru engineering"just put out that article saying how normal it is to burn oil and even had an illustration of a chick checking her oil.

APPLICABILITY: 2012 - 13MY Impreza Models with 2.0L FB Engines 2013MY XV Crosstrek
NUMBER: 02-145-13 DATE: 09/25/13
SUBJECT: Surface Treatment Change To Oil Control Piston Rings INTRODUCTION
This bulletin provides information regarding a change made to the surface treatment applied to the oil control piston rings for 2.0L FB engines. The change was made as a result of some limited fndings of unanticipated wear of these rings. Oil consumption will be higher than normal and consistent, if this wear occurs, the condition remains until repair. Unusual swings or variations in oil consumption are not consistent with this condition and may be the result of vehicle usage rather than the condition described here. Additional information is supplied in this bulletin to assist in the assessment and determination if vehicle usage is a reason for this varied oil consumption.
It is critical to understand the nature of the concern as reported by the customer and to confrm any actual condition prior to attempting any repairs. Some oil consumption can and should be expected as a by-product of engine operation where no concern exists. Failure to recognize this and correctly diagnose the condition presented can result in unnecessary repairs and in the worst case, an increase in oil consumption. The information supplied in this bulletin is only applicable to a limited number of vehicles within the specifc production range noted below exhibiting the condition(s) previously described.
It is important to read and understand this bulletin completely before starting an oil consumption test or initiating any repairs.
Customer concerns related to possible oil consumption are generally initiated by one of two scenarios.
• The customer reports the low engine oil level (not low engine oil pressure) lamp has illuminated.
• The customer believes the engine oil level on the dipstick has dropped when checking the oil.
Either of these situations by themselves does not directly indicate a concern with the vehicle exists beyond the need to add engine oil as part of normal maintenance. It is important to understand all the factors involved in order to make a sound decision regarding whether or not a repair is required or even if an oil consumption test should be started. When speaking with customers regarding a reported or suspected oil consumption concern, always keep the following information in mind:
Some engine oil will always be consumed as part of normal engine operation. How much and Continued...

it is consumed varies according to manufacturing tolerances, wear, and vehicle usage. With the extended service intervals commonly used for today’s engines combined with one or more of the conditions listed below, typical engine oil consumption may require the adding of engine oil in between scheduled maintenance intervals. If a customer inquires about oil consumption and is close to their next service interval, and consumption has not exceeded 1 quart in that time, the consumption rate should not be considered unusual. Consumption at a rate greater than this should be reviewed on a case by case basis after reviewing the vehicle’s usage patterns / history. Higher than expected oil consumption may occur under any of the following conditions:
• When the engine is new and within the break-in period (during the frst 3000 miles of operation)
• When the engine oil being used is of lower quality (other than “Energy or Resource Conserving” API Classifcation SM or SN or ILSAC, look for the starburst design with GF-4 or GF-5)
• When the incorrect oil viscosity is used (viscosity other than 0W-20 in the case of these specifc vehicles)
• When engine braking is employed (Downshifting to make use of the transmission’s gear ranges and the engine to decelerate the vehicle)
• When the engine is operated at high engine speeds (Continually or under frequent and repetitive hard acceleration such as frequent freeway merging)


• When the engine is operated under heavy loads (Frequent carrying of cargo, multiple passengers or trailer towing)
• When the engine idles for long periods of time (Frequent use of a remote engine start system followed by some period of idling as an example)
• When the vehicle is operated in stop and go and/or heavy traffc situations
• When the vehicle is used under severe temperature conditions (Cold or hot)
• When the vehicle accelerates and decelerates frequently
• Frequent short trip driving where the engine may not reach full operating temperature
Under these or similar operating conditions, the oil level should be checked regularly. The engine oil and flter may also need to be changed more often.
As related information, the engine oil low level warning light is designed to illuminate when the engine oil level in the sump is approximately 1.1 quarts low. This may vary with different driving and road conditions. Keep in mind that oil remains suspended in the engine while running and will not fully drain back until the engine has been shut off for at least 5 minutes. This is why waiting at least 5 minutes while parked on a level surface before checking the oil level is critical to getting an accurate gauge of the oil level in the engine. In some rare cases, this light may illuminate with more oil present when the engine is running due to specifc road or driving conditions such as repeated hard acceleration / deceleration, tight turning, driving on undulating roads. In these cases, the engine oil low level warning light will generally reset on its own once the actual level is determined to be above the illumination threshold. This reset process may take some time as certain driving parameters must be met for the system to self-correct. As long as the oil level has been checked and adjusted (if necessary), the immediate concern has been addressed. If the engine oil low level warning light does not extinguish on its own after some time and the oil level remains full, an inspection of the oil level sensor circuit and components should be performed.
NOTE: The engine’s specifed oil capacity is 5.1 US quarts for XV Crosstrek and 5.1 US quarts
for Impreza. Continued...

SERVICE PROCEDURE / INFORMATION
Before starting any repairs, the frst step is to always confrm the customer’s complaint. It is critical to get as much information from the customer as possible to allow for the most accurate diagnosis.
• Review all the available service and repair history along with any other records the customer can provide to establish whether or not the vehicle has been properly maintained.
• Perform a thorough visual inspection to make sure there are no external oil leaks that could be contributing to the condition.
• It is also very important to not overlook the engine’s PCV system and to confrm it is operating properly. Check the air flter assembly and throttle body / intake manifold for any excessive oil residue which could be an indicator of a sticking or failed PCV valve.
NOTE: An oil consumption test will need to be completed to determine the proper course of action. There is a specifc procedure and Oil Consumption Test form to be used with this bulletin ONLY. It can be located by accessing: Subarunet / Service / Forms / NEW FB Engine Oil Control Ring TSB Oil Consumption Test. The standard oil consumption test form and guidelines will still apply in all cases other than this bulletin. Once all the basics have been checked and the vehicle service history established, change the engine oil and flter to begin the oil consumption test. Always close the repair order on the day the oil change has been completed and submit the claim for the oil consumption test using the coding provided at the end of this bulletin. Indicate “Oil Consumption Test” in the comments feld / box when entering your claim. DO NOT hold the repair order open until the vehicle returns. Have the customer drive the vehicle then return for inspection when any of the following have occurred:
• At least 1200 miles have elapsed
• The engine oil low level warning light illuminates
• When the oil level reaches the lower hole in the dipstick/ gauge (as determined by the customer)
The customer should be advised to not add oil unless there will be a signifcant delay before they can return for inspection once a low oil level condition occurs. A one-time check of the oil consumption by the dealer is all that is needed to establish if the condition outlined in this bulletin applies. Continued...
